Nella Larsen, one of the most acclaimed and influential writers of the Harlem Renaissance, was born Nellie Walker on April 13, 1891, in Chicago. In the 1910s she came to New York, where she worked as a nurse and a librarian, and in 1919 she married a research physicist. She began publishing stories in the mid-1920s and published her first novel, Quicksand, in 1928. Passing came out the following year. Larsen was awarded a William E. Harmon Bronze Award for Distinguished Achievement Among Negroes and a Guggenheim fellowship. Encountering personal and professional struggles, she was unable to have her third novel accepted for publication and by the end of the 1930s had stopped writing altogether. She worked full time as a nurse until her death in 1964.
